PASADENA, Calif. -- NASA's Mars Science Laboratory is tucked inside its Atlas V rocket, ready for launch on Saturday, Nov. 26, 2011 from Cape Canaveral Air Force Station in Florida. The Nov. 26 launch window extends from 7:02 a.m. to 8:45 a.m. PST (10:02 a.m. to 11:45 a.m. EST). The launch period for the mission extends through Dec. 18.
The spacecraft, which will arrive at Mars in August 2012, is equipped with the most advanced rover ever to land on another planet. Named Curiosity, the rover will investigate whether the landing region has had environmental conditions favorable for supporting microbial life, and favorable for preserving clues about whether life existed.
On Nov. 26, NASA Television coverage of the launch will begin at 4:30 a.m. PST (7:30 a.m. EST). Live launch coverage will be carried on all NASA Television channels. For NASA Television downlink information, schedule information and streaming video, visit: http://www.nasa.gov/ntv . The launch coverage will also be streamed live on Ustream at http://www.ustream.tv/nasajpl .
If the spacecraft lifts off at the start of the launch window on Nov. 26, the following milestones are anticipated. Times would vary for other launch times and dates.
Launch
--The rocket's first-stage common core booster, and the four solid rocket boosters, will ignite before liftoff. Launch, or "T Zero", actually occurs before the rocket leaves the ground. The four solid rocket boosters jettison at launch plus one minute and 52 seconds.

Fairing Separation
--The nose cone, or fairing, carrying Mars Science Laboratory will open like a clamshell and fall away at about three minutes and 25 seconds after launch. After this, the rocket's first stage will cut off and then drop into the Atlantic Ocean.
Parking Orbit
--The rocket's second stage, a Centaur engine, is started for the first time at about four minutes and 38 seconds after launch. After it completes its first burn of about 7 minutes, the rocket will be in a parking orbit around Earth at an altitude that varies from 102 miles (165 kilometers) to 201 miles (324 kilometers). It will remain there from 14 to 30 minutes, depending on the launch date and time. If launch occurs at the beginning of the launch Nov. 26 launch window, this stage will last about 21 minutes.
On the Way to Mars
-- The second Centaur burn, continuing for nearly 8 minutes (for a launch at the opening of the Nov. 26 launch window), lofts the spacecraft out of Earth orbit and sends it toward Mars.
Spacecraft Separation
--Mars Science Laboratory will separate from the rocket that boosted it toward Mars at about 44 minutes after launch, if launch occurs at the opening of the Nov. 26 window. Shortly after that, the separated Centaur performs its last task, an avoidance maneuver taking itself out of the spacecraft's flight path to avoid hitting either the spacecraft or Mars.
Sending a Message of Good Health
--Once the spacecraft is in its cruise stage toward Mars, it can begin communicating with Earth via an antenna station in Canberra, Australia, part of NASA's Deep Space Network. Engineers expect to hear first contact from the spacecraft at about 55 minutes after launch and assess the spacecraft's health during the subsequent 30 minutes. The spacecraft will arrive at the Red Planet Aug. 6, 2012, Universal Time (evening of Aug. 5, 2012, PDT).

Curiosity at Work on Mars (Artist's Concept)This artist's concept depicts the rover Curiosity, of NASA's Mars Science Laboratory mission, as it uses its Chemistry and Camera (ChemCam) instrument to investigate the composition of a rock surface. ChemCam fires laser pulses at a target and views the resulting spark with a telescope and spectrometers to identify chemical elements. The laser is actually in an invisible infrared wavelength, but is shown here as visible red light for purposes of illustration. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington, and designed and built Curiosity.

NASA Launches Most Capable and Robust Rover to Explore Mars :
CAPE CANAVERAL, Fla. -- NASA began a historic voyage to Mars with the Nov. 26 launch of the Mars Science Laboratory (MSL), which carries a car-sized rover named Curiosity. Liftoff from Cape Canaveral Air Force Station aboard an Atlas V rocket occurred at 10:02 a.m. EST. "We are very excited about sending the world's most advanced scientific laboratory to Mars," NASA Administrator Charles Bolden said. "MSL will tell us critical things we need to know about Mars, and while it advances science, we'll be working on the capabilities for a human mission to the Red Planet and to other destinations where we've never been".

"MSL will tell us critical things we need to know about Mars, and while it advances science, we'll be working on the capabilities for a human mission to the Red Planet and to other destinations where we've never been".
The mission will pioneer precision landing technology and a sky-crane touchdown to place Curiosity near the foot of a mountain inside Gale Crater on Aug. 6, 2012. During a nearly two-year prime mission after landing, the rover will investigate whether the region has ever offered conditions favorable for microbial life, including the chemical ingredients for life.
"The launch vehicle has given us a great injection into our trajectory, and we're on our way to Mars," said MSL Project Manager Peter Theisinger of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "The spacecraft is in communication, thermally stable and power positive".
The Atlas V initially lofted the spacecraft into Earth orbit and then, with a second burst from the vehicle's upper stage, pushed it out of Earth orbit into a 352-million-mile (567-million-kilometer) journey to Mars.
"Our first trajectory correction maneuver will be in about two weeks," Theisinger said. "We'll do instrument checkouts in the next several weeks and continue with thorough preparations for the landing on Mars and operations on the surface".
Curiosity's ambitious science goals are among the mission's many differences from earlier Mars rovers. It will use a drill and scoop at the end of its robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover. Curiosity carries 10 science instruments with a total mass 15 times as large as the science-instrument payloads on the Mars rovers Spirit and Opportunity. Some of the tools are the first of their kind on Mars, such as a laser-firing instrument for checking rocks' elemental composition from a distance, and an X-ray diffraction instrument for definitive identification of minerals in powdered samples.
To haul and wield its science payload, Curiosity is twice as long and five times as heavy as Spirit or Opportunity. Because of its one-ton mass, Curiosity is too heavy to employ airbags to cushion its landing as previous Mars rovers could. Part of the MSL spacecraft is a rocket-powered descent stage that will lower the rover on tethers as the rocket engines control the speed of descent.
The mission's landing site offers Curiosity access for driving to layers of the mountain inside Gale Crater. Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history.
Precision landing maneuvers as the spacecraft flies through the Martian atmosphere before opening its parachute make Gale a safe target for the first time. This innovation shrinks the target area to less than one-fourth the size of earlier Mars landing targets. Without it, rough terrain at the edges of Curiosity's target would make the site unacceptably hazardous.
The innovations for landing a heavier spacecraft with greater precision are steps in technology development for human Mars missions. In addition, Curiosity carries an instrument for monitoring the natural radiation environment on Mars, important information for designing human Mars missions that protect astronauts' health.
The mission is managed by JPL for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL. NASA's Launch Services Program at the Kennedy Space Center in Florida managed the launch. NASA's Space Network provided space communication services for the launch vehicle. NASA's Deep Space Network will provide spacecraft acquisition and mission communication. United Launch Alliance, Denver, Colo., provided the Atlas V launch vehicle.
